What this cable adds

This RIITOP bracket cable converts a single 20-pin motherboard header into two external USB 3.0 Type-A ports. It is aimed at desktop builders who need extra front or rear connectivity without consuming a PCI expansion slot. The 50 cm length suits standard ATX and micro-ATX chassis layouts.

Thermals noise and power

The assembly is a passive copper cable with no active electronics, so it generates no measurable heat and produces zero acoustic noise. Power for connected devices is drawn directly from the motherboard header, limited by the board's own USB 3.0 current implementation.

Build and daily use

A metal bracket secures the two ports to a rear case cutout, giving a firm mount that resists cable strain during frequent plug cycles. The blue 0.5 m cable routes cleanly behind the motherboard tray, and the 20-pin female connector keys into the header in one orientation only.

Questions about this item

How do I fit the 20-pin header onto the motherboard and where does the bracket screw in?

Plug the 20-pin female connector into the motherboard USB 3.0 header, then secure the metal bracket to a rear chassis opening with the case screw.

Will the blue 50 cm cable or the two USB 3.0 ports wear out and need replacing?

The cable and ports are passive; they only need replacement if physical damage occurs.

What happens to transfer speed when both ports run at 5 Gbps for a long time?

Each port shares the single 20-pin header bandwidth, so sustained dual-port use may reduce per-port throughput.
